Microsoft slices Windows 11 update size by 40% (no, not by cutting hardware support)
Microsoft is boasting of how it reckons to have reduced the size of Windows 11 updates. Surprisingly "cutting hardware support" didn't feature. The monthly cycle of fixes for Microsoft's wares has been the bane of many an administrator's life over the years. The operating system's decision to go for a lengthy lie-down at …

I'm confused...
Wouldn't taking a system-wide snapshot prior to applying the updated bits, rebooting to apply them, & asking "Is it working correctly?" after the restart do the job quicker & easier? If the customer clicks yes then the computer continues as normal. If they click no then it reboots, restores to the snapshot, & sends a crash report to MS to let them know it didn't work.
What, probably obvious, aspect am I missing that bloats the whole thing so far beyond it's basic needs?
*Sets out pints of beer for the folks that answer instead of merely downvoting me into oblivion* Thanks!

A "retro-date", where you claim you didn't even meet them, much less go out on a date where they described each of their many tattoos and who each of those were about and why those people were really bad people they no longer associate with and the details 'why' for each person at length.
Sort of like what you want when Microsoft's updates go wrong, yes? Let's pretend it never happened...

Re: I'm confused...
What you're suggesting should work well, seeing that is pretty much what I've been doing with Fedora Linux updates for the last 15 years or so:
- make a backup with rsync onto a USB HDD
- disconnect the USB drive
- run dnf to download and apply updates
- reboot
I've not had any problems so far.

Re: I'm confused...
How large is the snapshot and does the machine have room for it? (Consider especially old laptops.)
How soon will you find out that the update's broken or damaged something? (Only extreme errors stop systems rebooting to familiar desktops.)
If you do find a problem a day or a week later, how will you selectively roll back the specific problematic update without losing all the other configuration and installation you've done in that day or week?

"How large is the snapshot and does the machine have room for it? (Consider especially old laptops.)"
You are joking? I don't believe "Windows 11" and "old laptops" are allowed to be used in the same sentence excepting possibly "Why would anyone bother installing Windows 11 on old laptops?"

Re: I'm confused...
I guess* what they're actually doing is just saving the parts of files that were modified during the update.
If the update delta, for example, contains replacement data for the bytes 1400-1900 of file A, then only those bytes need to be saved to be able to roll file A back to its original state. If file A happened to be 10MB in size, that's a considerable saving.
Not exactly rocket science, and not something I would have bothered trying to patent (or something I would grant a patent for if it came across my desk). But in these dark times if you don't patent it, someone else will, and getting a patent invalidated probably costs 100 times as much as the patent application in the first place. *sigh*
* If I really cared, I could go and read the patent for myself, but I really don't, so I won't.

Re: I'm confused...
I guess for CoW snapshot to work Windows system protection has to be enabled with certain amount of free disk space. M$ engineering may not be confident enough on roling back entire file system due to lack of disk space etc. E.g. one may have created a business file and now the files system is rolled back and the file is gone. Another reason behind delivering forward and reverse updates is one can remove one or more updates (patches) individually as opposed to complete roll back. Why commit a complete roll back of multiple patches when you may only need removing a patch or two. Either way it may be pointless, after uninstalling a patch Windows will keep trying to apply the patch unless the patch is unapproved in corp environments, which regular users can’t.

Re: Windows 11, same as Windows 10
Not sure I follow you here.
Is it the new code that's causing the problem because it's new? Or is it the old code that hasn't been patched in the past?
Or is it, as I suspect, simply code written by someone at Microsoft and therefore in your opinion it's bad no matter whether it's new or old?

A patent for something that obvious? It doesn't strike me as a particularly novel step to generate the reverse diff as you apply the forward diff. I don't know if anybody does this. It strikes me as a bit risky (restoring the previous state vs restoring a known good state; discuss). But it wouldn't surprise me to find prior art.

My computer s windows 11 compatible, as I've just ripped the guts out and upgraded, due to heating issues, but -
Wife's 3 year old Ryzen 1800X ROG 32GB RAM TPM2. and secure boot enabled not compatible - all because Microsoft say the original Ryzen is not compatible although its ROG, with twin AMD 8GB graphics cards - They can shove it - I'm buggered if I'm paying even more money to upgrade the processor, and MB
We got a 12 year old Lenovo,laptop, which is running windows 10 pro, 64bit and is bang up to date. Yes its slow to boot, but it works fine once booted. Now that I would agree not to be supported, but NOT a 3 year old computer, which cost me over 2K MICROSOFT . GRRRRRRRRR

Swap out the old laptop hard disk for an SSD and give it a new lease of life.
Just make sure the SSD is bigger (not difficult given its 12 years old), then with a Linux live memory stick, just dd across the old disk to the new one and you are done. Or find a manufacturer upgrade tool that will do the same on Windows.

Re: Wouldn't it be simpler...
Yes.
Not only.., but also: Anyone developing for the OS will not have a moving target to contend with. How much bloat is there in software if it has to detect the presence or absence of updates that affect it? In some cases none, but then software vendors have to maintain significant helpdesk resources to deal with the arising flak, which may include web-based boards where people have a problem, ask a question, then get bombarded with "have you got the latest update?", "remove xyz update, it is evil", etc.
Every update increases the possibilities. It is easy to see they rise exponentially, making third-party products unmaintainable.
